Windows FPS not reaching max FPS despite Debug Overlay FPS > 60

[GrizzliusMaximus]

I did a simple stress test, draw 8000 bears (each bear is an object) onto the screen. I did the same exact test with GMS 1.4 and at first, it looked like GMS 2 was performing better, but my eyes were telling me something was lagging so I debugged the FPS using the built-in FPS variable and compared it with the Debug Overlay FPS. Here are the results:

GMS2:

GMS1.4:


Here is the creation code of the room:

GMS2:

show_debug_overlay(true);
display_set_timing_method(tm_sleep); // removing this line give the same result
game_set_speed(60, gamespeed_fps);
instance_create_depth(0,0,0,object1);
for (var i = 0; i < 8000; i++){
    instance_create_depth(random(280)+20, random(140)+20,0,obj_bear);
}

GMS1.4:

show_debug_overlay(true);
instance_create(0,0,object1);
for (var i = 0; i < 8000; i++){
    instance_create(random(280)+20, random(140)+20,obj_bear);
}

As you can see, the fps reading in the debug overlay for GMS 2 looks better than GMS 1.4 but GMS 1.4 manages to reach about 60 fps while GMS 2 hardly reaches 30. Both versions have FPS capped to 60. Vsync toggled on/off give the same result.

object1 displays the fps if you are wondering.

Would be best if you could post the projects for testing.

xxxxxxxxxxx,,,, man you show debug comend,,, not

In my game fps_real is always way higher than what the actual FPS is. For example I start dropping below 60 FPS when fps_real is around 200. I assume you are using all the same build options VM/YYC

I'm getting a fixed 60 FPS on that project, I even increased the number of objects to the point where the fps_real dropped below the one you have in your image, but was still maintaining 60 FPS. Would you happen to be on a laptop with both integrated and dedicated GPUs?

I have a feeling this is my problem. Yes. I am currently abroad and it will be more than a month till I can return to my beautiful desktop. My laptop is pretty old (intel HD graphics with intel pentium) and when I was deciding to get a decent laptop or a beast desktop at a lower price, I chose desktop. I don't really regret my choice though.

Thanks for testing! I think this is just a GPU problem and not GMS. Still I wonder why GMS 1.4 was able to handle the load better.

Maybe GMS 2 is using layers and GMS 1 doesn’t? More processing causing slight slowdown? Idk just throwing that out there.

I have had people have issues with my game using the integrated GPU of their computer instead of their dedicated. This caused bad performance. I don’t know if there is any way to have a game prefer a dgpu. They all just had to manually set the game to use it

You should try playing with the sleep margin and timing methods. I've read before that changing from the default timing method to tm_sleep can solve the issue, as can raising/lowering the sleep margin. Might be worth experimenting with this... like check the FPS and if it's below 60 then change the sleep margin/timing method. Another fix I've seen is for you to quickly switch between windowed and fullscreen a couple of times on startup. For some reason that seems to stabalise the FPS (something related to the OS and power saving or something like that...)
